摘要： PROBLEM TO BE SOLVED: To provide a blower device and a vehicular air conditioning device capable of reducing noise at low cost and with high reliability. SOLUTION: In a diffuser part 51, a projection part 60A projecting toward the inside of the diffuser part 51 is formed on a side face 51a near a rotary shaft of a fan 21a at a position adjacent an opening part 52c of an inlet flow passage part 52. By an air stream sent out from the fan 21a colliding with the projection part 60A, the air stream near a position corresponding to the center of a blowing port 22a is locally raised in pressure, and the flow of the air stream is deflected to a side away from the sides of upper and lower faces 51c, 51d which are relatively low in pressure. As a result, inside the diffuser part 51, the air stream is dispersed in the enlarging direction of a flow passage of the diffuser part 51, the distribution of the air stream inside the diffuser part 51 is made uniform, and an increase of noise and fluctuation of the wind amount are suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of suppressing generation of noise in a unit housing by air flowing-in from a blower.
SOLUTION: By providing a reflection surface 60A for reflecting a pressure wave transmitted from an air-feeding part 22 toward an opening part 52c on an inlet flow passage part 52 of the unit housing 50H, the pressure wave transmitted from the air-feeding part 22 is avoided from being reflected/returned to the air-feeding part 22 side. Thereby, in the unit housing 50H, for example, by variation of a cross section area of a flow passage in a diffuser part 51, even if pressure variation is generated caused by peeling off or the like from an inner wall surface of the diffuser part 51 on the flow of air fed from an air-feeding unit 20, interference by reflection of the pressure wave is prevented from being generated and generation of noise caused by the variation of the pressure is suppressed.
